The co-seasonal application of anti-IgE after preseasonal specific immunotherapy decreases ocular and nasal symptom scores and rescue medication use in grass pollen allergic children.

BACKGROUND: Specific immunotherapy (SIT) and treatment with anti-immunoglobulin (Ig)E antibody are complementary approaches to treat allergic rhinoconjunctivitis, which may be used for single or combined treatment. OBJECTIVE: A randomized, double-blind, placebo-controlled trial was conducted to compare the efficacy of single and combined treatment with SIT and anti-IgE (Omalizumab) in reducing symptom severity and rescue medication use. METHODS: A total of 221 subjects with birch and grass pollen allergic rhinoconjunctivitis aged 6-17 years were analysed during the grass pollen season. Group A (SITbirch + placebo) served as a reference group obtaining no effective treatment for grass pollen allergy. Group B received anti-IgE monotherapy during grass pollen season, group C SIT grass pollen monotherapy, and group D the combined treatment of SIT and Omalizumab. RESULTS: Preseasonal treatment with grass pollen SIT alone compared with SIT with the nonrelated allergen did not reduce symptoms or rescue medication use. Anti-IgE monotherapy significantly diminished rescue medication use and number of symptomatic days. The combined treatment with SIT and anti-IgE showed superior efficacy on symptom severity compared with anti-IgE alone. CONCLUSIONS: Co-seasonal Omalizumab therapy showed considerable effects in children with seasonal allergic rhinitis. The combination of SIT plus Omalizumab was clinically superior to each treatment alone during the first year of observation.

Efficacy and tolerability of terbinafine 1% topical solution used for 1 week compared with 4 weeks clotrimazole 1% topical solution in the treatment of interdigital tinea pedis: a randomized, double-blind, multi-centre, 8-week clinical trial.

In this double-blind clinical trial 429 patients (217 terbinafine and 212 clotrimazole) were randomized to receive twice daily terbinafine 1% topical solution for 1 week followed by a vehicle application for 3 weeks, or 1% clotrimazole solution for 4 weeks. Patients were evaluated clinically and mycologically at baseline and then at weeks one, two, four (end of treatment), and eight (end of follow-up). To be evaluable the patient needed to have a positive culture for a dermatophyte and positive KOH microscopy and a clinical diagnosis of tinea pedis (interdigital type) at baseline. Effective treatment of tinea pedis was recorded in 181 of 217 (83%) of patients treated for 1 week with terbinafine 1% solution and 174 of 212 (82%) of patients treated for 4 weeks with clotrimazole 1% solution. Mycological cure and disappearance of signs and symptoms were similar at each assessment visit in the two groups. In the subgroup of patients without any protocol violation the mycological cure rate was 95% (164 of 173) with terbinafine solution and 91% (159 of 174) with clotrimazole solution (P = 0.05). Adverse events believed to be drug-related occurred in 13 patients in the terbinafine group and 11 in the clotrimazole group (4 to 5% in each group). The events were primarily local skin reactions of mild to moderate intensity. It can be concluded that terbinafine 1% solution used for 1 week to treat tinea pedis is well tolerated and at least as effective as clotrimazole 1% solution used for 4 weeks.

Different concepts in first-line treatment of essential hypertension. Comparison of a low-dose reserpine-thiazide combination with nitrendipine monotherapy. German Reserpine in Hypertension Study Group.

Low-dose combination therapy has been proposed as a rational first-line approach to hypertension treatment. We compared the efficacy and tolerability of the fixed combination of reserpine (0.1 mg) plus the thiazide clopamid (5 mg) with its single components and the calcium-antagonist nitrendipine (20 mg) in a randomized, double-blind, parallel study of 273 hypertensive patients with diastolic blood pressure (BP) between 100 and 114 mm Hg. The four groups did not differ regarding baseline characteristics (mean age, 58 years; 51% men; mean BP after a 2-week placebo period, 158 to 160/103 to 104 mm Hg). After 6 weeks of treatment with one capsule daily, mean reductions in sitting BP from baseline at 24 hours after dosing in the reserpine-clopamid combination, reserpine, clopamid, and nitrendipine groups were -23.0/-17.1, -14.0/-11.7, -13.6/-11.9, and -11.6/-12.3 mm Hg, respectively (2P < .01). The corresponding normalization rates (diastolic BP < 90 mm Hg) were 55%, 40%, 36%, and 33% (2P = .11). All patients whose BP had not been normalized at this point received two capsules of the respective medication once daily from weeks 7 to 12. At week 12, mean BP reductions were -25.7/-18.1, -14.6/-12.2, -17.7/-13.4, and -14.9/-15.3 mm Hg in the four groups, respectively (2P < .01). The respective normalization rates were 69%, 35%, 39%, and 45% (2P < .0001). Linear regression modeling indicated that reserpine and clopamid combined acted more than additively. As regards tolerability, adverse experiences were observed in 27%, 28%, 29%, and 48% of patients, respectively (2P < .05). The respective rates of premature discontinuation because of adverse effects were 3%, 3%, 7%, and 13% (2P = .06). In conclusion, a low-dose combination of reserpine and clopamid lowered BP significantly more than both the components alone and nitrendipine. Moreover, the combination was tolerated as well as its components and significantly better than nitrendipine. Thus, the use of this low-dose reserpine-thiazide combination appears to be a rational alternative to conventional monotherapy in the first-line treatment of hypertension.

[Therapy comparison between the combination hydergine/nifedipine and nifedipine alone in patients with isolated systolic hypertension]. / Therapievergleich zwischen der Kombination Hydergin/Nifedipin und Nifedipin bei Patienten mit isolierter systolischer Hypertonie.

The effect of Hydergine/Nifedipine (Pontuc) on blood pressure in supine or exercise blood pressure as well as subjective well-being was evaluated in a randomized, double-blind interindividual comparison with Nifedipine in 50 elderly out-patients (34 females, 16 males) with mostly pretreated isolated systolic hypertension. In addition to a nearly unchanged diastolic blood pressure during treatment the results prove that the drop in systolic blood pressure was statistically significant greater after treatment with Hydergine/Nifedipine and the normalization rate of the blood pressure was 81% in comparison to 69% after Nifedipine. Both drugs comparatively improved the subjective well-being of these geriatric patients. As drug specific adverse events flush symptoms were more frequent in the Nifedipine group, whereas in the Hydergine/Nifedipine group gastrointestinal symptoms occurred more often.

Calcium antagonists as first-line antihypertensive agents: a placebo-controlled, comparative trial of isradipine and nifedipine.

The new calcium antagonist isradipine was compared with nifedipine retard in a multicenter, double-blind, placebo-controlled, randomized study involving 159 patients with mild hypertension. A 2-week run-in period was followed by a 6-week course of treatment with the possibility of dose doubling after 3 weeks, depending on blood pressure (BP) response (target diastolic BP less than 90 mm Hg). Systolic and diastolic BPs were reduced by isradipine (mean dose of 3.6 mg daily) from 151/101 to 136/89 mm Hg, by nifedipine (mean dose of 50 mg daily) from 155/101 to 144/90 mm Hg, and by placebo from 155/101 to 154/99 mm Hg. Normalization rates were 64% with isradipine, 56% with nifedipine, and 16% with placebo. Adverse events consisted mainly of flushing, headache, edema, and dizziness. Altogether, 8 patients receiving isradipine experienced adverse events in comparison to 21 taking nifedipine and 4 taking placebo. The superior tolerability of isradipine was paralleled by a significant improvement in the subjective well-being of the patients as assessed by the von Zerssen questionnaire (List of Complaints). With nifedipine and placebo, no statistically significant improvement was observed.
